My LS1 Build.....

[trapin]

Trey...do you think I should switch to the PRC 5.3 stage 2.5 heads from Texas Speed? I can get them in 2.02/1.55 or 2.04/1.55 and they are 220cc. They would bump up compression at bit too. 10.75:1 as advertised.



Would that cam sound wimpy in my car or would it still have a nice lope to it?

Thanks Trey, you've been a big help so far.

[marine02ss]

I build a 2002 RaM Air with AFR 205s and the exact same camshaft we made 423rwhp and ran an 10.80n/a full weight car.It does clear a stock motor no valve reliefs needed if the motor is stock.

[Steve68]

Damn!

[trapin]

Marine....the TSP 228R or the Torquer v2?

Impressive numbers.

Isn't it cute...Tony's talking in lingo now

How fast they grow out of thier SBC's and into thier GEN III's

A few things to consider I'm just throwing out there... Have you thought any about the futral cams? They seem to be amazing cams. Also I would recommend the dart heads for best bang for the buck. They flow great out of the box and with alittle porting and polishing they are really good heads. Also I wouldnt recommend going any lower than a 114 lsa. 112 I think would be too much for an auto. Also I would for sure stay under a 3000 rpm stall for ease of driving. Then don't forget the dual springs. PRC seems to be the way to go on this. Just throwing out some opinions and other views. It is ridiculous the different aftermarket companies for the LSx series motors and it's very hard to keep up with them.

This is so true.

Tony, the 228/228 will have a nice sound to it I think, but it's nothing heavy. You will know it is cammed though. The biggest problem with making newer cars sounds so cammed compared to the old SBC is the EFI. It allows the car to be tuned so well for all conditions. Most people that hear a nice lope in an old car aren't necessarily hearing a well tuned car which simply adds to the lope sound.

I would just go with the ported LS6 heads for now. It's not at all that the LS6 heads are some how a bad choice or will perform poorly. Just the opposite is true. I just simply have my preferences and beliefs and they may not go to well with your budget. You should still make 400 rwhp minimum and torque should be close to that with that combo. The 2800 stall will do perfectly fine for a pro-touring car. Make sure you have an external trans cooler for the fluid though. Do get the 114 LSA also. The trans will like it better. That's the one draw back to the electric trans, they can be so finikey with a cam on the street.

You can nit pick a combo to death trying to get that last bit of power out of a car. I say keep it simple so you can drive and enjoy the thing. That combo is simple and works well. Go with it. If you want more later, you can easily do so because it's simple right now.

LMAO! The addiction is strong with this one

[trapin]

LOL!!! Marsa you dog.

It's true though...I'm a man possessed.

Thanks for the advice Trey, Christian....I'm going to stick with that combo. Now I just need some money to buy it.

[Steve68]

I like that came too I just might have to jump on the Trapin cam band wagon,

I've already started gathering parts for the LS Nova swap, I think a nice LS1/2 with a procharger would be fun, modern,

[trapin]

Hop on, man!

For reference, here's what it's going to look like. This is it, the final build specs. These are all the mods that are going to be done.....

- TSP 228/228 .588/.588 lift 114 lsa
- PRC 5.3 CNC Ported Heads 2.02/1.55 valves
- LS6 Intake
- 30 lb Stock Injectors
- Stock Throttle Body (ported/modified)
- LS2 Timing Chain
- LS6 Ported Oil Pump
- Chrome Moly Push Rods
- LS6 PCV Intake Valley
- 2800 stall convertor

Texas Speed strongly recommended those heads for this camshaft and John says it should flirt with 500 horsepower at the crank. That's all the power I'm ever going to need in this car.

.......for now, anyway.

[Steve68]

Mine:
Dart Pro 205/225 heads hand exhaust port work done
TSP or MTI cam close to the same specs
LS6 intake
30lb injectors
ported T/B
LS6 ported oil pump
7.4 C/M pushrods
S/W headers X pipe Rhino RPM mufflers
T-56 spec F/W Ram clutch Pro5.0 shifter,

This should be it, but why the LS2 chain and the LS6 intake valley, whats this do??

[JChristian1835]

The LS2 timing chain is thicker and more durable...

and with the ls6 intake valley.. the only thing i can think of being a benefit is maybe the ls6 pcv setup??

[WS6]

Yep, that's correct on both accounts Christian and Steve.

Many people have switched to the LS6 PCV system which requires an LS6 valley cover. This helped in oil consumption through the TB. However, I know people that have done this swap and it hasn't helped enough. Running a catch can isn't a bad idea if you are sucking oil up through the TB. Do a search on LS1Tech.com and there is a company making quality catch cans that would look right at home on a detailed engine. I can't remember their name though.

Also make sure you change your sprockets out Tony and anyone else doing a build. You will find a lot of people only swapping to the LS2 chain and keeping their old sprockets becuase they see no wear on the sprockets This is ludicrous. The whole setup is $90. Just because you don't see any wear on the sprockets doesn't mean it's not there.

VERY VERY valid point.... alot of problems with people reusing sprockets.

[trapin]

Damn, I wish I would have known this sooner. I already ordered just the chain because TSP told me the old sprockets would be fine. I wonder If I could get just the sprockets somehow.

Also, in regards to the LS6 PVC system...I'm doing it to hopefully remedy the oil consumption because although I know some have not had success with it, some have, and I'm hoping to be one of them. It also eliminates a lot of hosing on the engine which helps to clean up it's appearance some. For $55 I felt it would be worth it. I'll look into running a catch can too though. Thanks guys.

Yes you can order just the sprockets.. and there really isnt a good way to inspect them for good integrity

[JChristian1835]

The LS2 crank sprocket is part number 12556582 and it is pretty much the same as the LS1 sprocket. Since they are practically the same I think that they would be interchangable. The only difference I can tell or have heard is that the LS2 cam gear is specifically made for the cam position sensor.

[marine02ss]

The cam Im talking about is the Thunder Racing Trak cam 231/235

[bigtyme1]

Tony, what was your final build? did you go with the patriot? is it running good?
